Simulation modeling

Definition

Simulation modeling is a technique used to create a digital representation of a physical system or process, allowing for the analysis and prediction of its behavior over time. This method is particularly useful for understanding complex systems, such as multiple reaction systems in chemical engineering, where various reactions occur simultaneously and interact with each other. By using simulation modeling, engineers can optimize processes, evaluate different scenarios, and make informed decisions based on predicted outcomes.
